Arffiaz' fizylrei'mazz ATTORNEY United States Patent Qfifice 3,287,853 Patented Nov. 29, 1966 3,287,853 METAL WINDOW HAVING A SLIDABLE AND SWINGING SASH Arthur Silverman, 55 Dorison Drive, Short Hills, NJ. Filed Aug. 5, 1964, Ser. No. 387,622 1 Claim. (Cl. 49-179) This invention relates to metal windows and particularly to a metal window having a slidable and swinging hinged sash.

This invention has for its salient object to provide a metal window with a hinged and slidable mounting and with a latching bar for the swinging window that can be easily released and will not vibrate and chatter.

Another object of the invention is to provide a metal window having a hinged and slidable sash mounting that is simple and practical in construction and can be economically manufactured.

Further objects of the invention will appear from the following specification taken in connection with the drawing which form part of this application and in which:

FIG. 1 is a front elevation of a window embodying the invention;

FIG. 2 is a front elevation similar to FIG. 1 but partly broken away and showing the window sash partially raised and swung inwardly on its hinged edge;

FIG. 3 is a transverse sectional elevation on an enlarged scale taken substantially on line 3-3 of FIG. 1 looking in the direction of the arrows;

FIG. 4 is an elevational view partly in section taken at right angles to FIG. 3 and showing one of the hinges in elevation;

FIG. 5 is a sectional elevation of one edge of the window, partially open, and the latching bar which coacts therewith to latch the window in closed position;

FIG. 6 is a vertical sectional elevation on an enlarged scale showing the window sash and latch bar; and

FIG. 7 is a perspective elevational view of one of the hinges.

In the particular embodiment of the invention illustrated in the drawings, the window frame at the two edges of the window sash is illustrated at 10 and 11.

The window sash of the lower window is slidably mounted and is also mounted at the left-hand side of the sash as shown at- 13 for pivotal movement on a pair of hinges 14 and 15. Each of the hinges has a base member 16 to which has pivoted thereto at 17 a pivoted hinge portion 18 which is secured to the window sash. The base member 16 as shown particularly in FIG. 7 is channeled and has a main portion and parallel side or flange portions 19 and 20 which are connected together at one end by said main portion and are seated in a channel or guideway that is formed by a vertical bottom wall and spaced and parallel window frame members 21 and 22 the flange portion have their free ends abutting said vertical bottom wall. These frame members have inwardly extending end portions 23 and 24 which embrace portions 25 and 26 of the base of the hinge adjacent to but spaced from the first-mentioned ends of the flange portions.

The hinges are preferably made of resilient plastic material and are slidably mounted in the window frame in the guideway formed by the frame portions 21 and 22. Initially the base portions are slide into the guideways from one end thereof, the flange portions being resiliently flexible toward and from each other and each thereof resiliently slidably engaging one of said frame members. The left-hand side of the window sash to which the hinge portions 18 are secured comprises front and back portions or walls 30 and 31. The wall 30 secures and encloses one of the outer edges of the window pane 32, the pane being held by the wall 30 against a wall portion 33 as shown in FIG. 3. The hinge portion 18 is secured to a wall 34.

The other edge of the hinged sash is secured in closed position against the right-hand edge 40 of the window frame by means of a channel-shaped latch bar 41 which is resiliently actuated in an outward direction by several bowed spring strips 42, as shown particularly in FIG. 6. The latch bar 41 is mounted in a box-shaped recess in the right-hand side of the window frame, this recess being designated at 53. The channel-shaped latch bar 41 has flanges 43 and 44 which engage flanges 45 and 46 on the window frame and limit the outward movement of the latch under the action of the spring strips 42.

The right-hand side of the window sash has portions forming a channel within which the latch bar 41 seats as shown in FIG. 3. The channel is formed by frame members 47 and 48. The right-hand side of the pane is held between wall portions 49 and 50 of the window frame.

The window frame also has a wall extension 51 which encloses or forms a guide for a sash wall 52.

When the window is to be swung inwardly as shown in FIG. 2 for cleaning, it is raised to the position shown in FIG. 2 and then the latch bar 41 is pushed inwardly against the action of the spring strips 42, thus releasing the channel-shaped latch bar from the channel formed at the right side of the sash. FIG. 6 illustrates the position taken when the lower end of the latch bar has been pushed to the right and this is also shown in FIG. 5. As the window is swung outwardly the latch bar is released from the channel at the right-hand side of the sash and the sash has a sliding action on the latch bar during this releasing movement.

The latch bar and the resilient spring strips 42 are preferably formed of resilient plastic material and when the latch bar has seated and the window is latched, due to this material, the window is firmly held in closed position without vibration and chatter.

It will be understood by those skilled in the art that a sash balance of any known or suitable type may be utilized, for example a torque spring having one end connected to the frame and the other end subjected to torque by a helical rod one end of which is connected to the upper hinge the base portion 16 of which is provided with an opening for a screw or the like to connect the rod to the hinge.

Any suitable means may be provided to facilitate raising of the sash, but in the drawing the finger bar 54 is shown as connected to the lower rail of the sash.

Although one specific embodiment of the invention has been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and arrangement of the various parts may be made without departing from the spirit and scope of the invention as expressed in the following claim.

I claim:

A window including a metal Window frame, a window sash, said frame having a vertical channel at one side of the window sash including a vertical bottom wall and spaced and parallel frame members each having an end portion inturned toward and in spaced and opposed relation to the end portion of the other frame member and in spaced relation to said bottom wall, hinges at said one side of the window sash, each hinge including a base member of inherently resilient synthetic plastic material having a main portion and spaced apart parallel flanges connected together at one end by said main portion and resiliently flexible toward and from each other and each resiliently slidable engaging one of said frame members of said vertical channel with its free end slidably abutting said bottom wall, said base member also having portions adjacent to but spaced from the other ends of said flanges in slidable engagement with said inturned ends of said frame members, each hinge also including a hinge portion pivotally connected to said base member and secured to said side of said sash.
